Science
Mechanism of Action
As a type of polysilsesquioxane, this ingredient forms a fine, imperceptible film upon application to the skin. Related spherical silicone powders within this class are known to create a smooth, soft texture and can visually minimize the appearance of pores and fine lines through light diffusion, a 'soft-focus' effect. Its structure aids in mattification by helping to manage excess surface oil. While the precise mechanism of the 'dimethylaminobenzamidopropyl' group is not fully elucidated in the available literature, it is inferred to contribute to conditioning or specific surface interactions, tailoring the ingredient's performance.

Safety Profile
The Cosmetic Ingredient Review (CIR) Expert Panel has thoroughly assessed the safety of 18 polysilsesquioxane ingredients, including Polymethylsilsesquioxane, concluding they are safe for use in cosmetic applications at current practices and concentrations. The highest reported maximum concentration for a related polysilsesquioxane, Polymethylsilsesquioxane, is 55.2% in certain makeup preparations, while other polysilsesquioxanes are typically used at 4.9% or less. Ingredients within the related Methicone family are also deemed safe by the CIR Panel. Comprehensive testing has consistently demonstrated that polysilsesquioxanes are non-irritating and non-sensitizing to the skin.
